Assemble five or six old clay flower pots and decorate them on the outside with either magic marker or paint.
Try to make each design distinctive.
Place all the pots into a large paper bag or old pillow case and close the top.
With a hammer, gently bang on the pots inside the bag until they are all broken into pieces.
Shake the bag several times and dump out half the pieces.
Using white glue, try to reassemble as many of the original pots as you can.
Variation
You can make this game more difficult by having one person do the
first 4 steps. Then the kids can try to reconstruct the pots
they've never even seen. Have an extra pot available in case
you need to show them the shape of the finished pots.
